T0 ALL WHMIT MAY CONCERN v Be it known that I, JAMES VC. DUNCAN, of Olney, in the county of Richland, and' State of Illinois, have invented :rv-new and uset'ul improvement in Portable Fences; and I do herebydeclare the following `to be e full, clear, and exact description 4of the same, reference beingv had to the accompanying drawings Whicharev made part oi' this specification, and in which- Figure fis an end elevation of my improved fence. Figures Zand 3 are side eleva-tions. V l Figure 4 is a detached' view. A Similar letters of reference indicate corresponding parts in the several figures. Theobject of rny invention is to obtain a simple, cheap, and durable fence, which can 'be built vrput up with facility, and which shall not be liable to injury from shrinkage. To this end it vconsists in a novel construction of trestle or support for sustaining the e'nds of the lulnber, rails, or poles which make up the fence, which may be' either afield, stock, or other' enclosure. y 'Y i l i v In order that others skilled in the art to lwhich my invention .appertains may be enabled to fullyfunderstand and usc-,the same, I will proceed to describe it in detaihyIn the drawings, A may represent latfluibcr rails, but Yinstead thereof the ordinary split rails or=poles i may be employed. The ends of .the rails A are confined between the upright parallel-batterie C C, which arc connected together by the transverse pins D and keysV d, the ends of vthe rails resting on the pins D, as represented in fig. 4. Each pair of battens C C is supported laterally by means of the converging braces-E E, the uppercnds of which are secured to thc battons by one of the pins D which support the rails. lThe lower ends ot' the braces E E extend below the fence, and are suitably embedded 'inthe ground to vgive steadiness and. rigidityl tothe fence laterally. A cross-tic or bar-, F, connects the lower ends of.' the braces to the battens, as represented in fig. 1. The supporting trestlcs, constructed as above described, are vbraced andsteadied asunder by notching the ends of one ot' the rails, say the upper one, so'as to cause the same to engage over -its supporting pinsl), (sce tig. 4.) The lower rail roar rest upon the ground'orbe sustained u. little above the same by'a block or st0nc.-

The trestles above described can. bemaimtaeturcd cheaply, and with theirad the fence'can-be set up with great facility. A fence thus built is durable, not boing liable to shrinkage, and the material of the' structures may be produced in various ways, as by sawing or splitting. The number of rails may be va-'ried as represented in the drawing. The entire structure may be built without the use of sawcd timber,'as the material 'generally vfound in the bauds ofthe farmer will sudice.

,bined substantially in tbe'manncr and for the purpose specified.'

v .-I de not claim the battons C C, braces E 'E, or pins D D, separately considered, as I am aware that these points in themselves are not new. l Y l Havin,r thus described my invention, what I claim as new herein, and desire to secure by Letters Patent, is-

'Ihe supporting trestlc, consisting of the battens C C, braces E E, pins D, rail.s A, and cross-tie com- JAMES O. DUNCAN. Witnesses:
